摘要： A dispensing container is disclosed which includes a fiber tube, a bottom end closure, and a top end closure which is self-locking on the fiber tube. The self-locking top end closure includes an annular skirt portion which is received in the tube and a cantilever fin which projects radially outwardly from the skirt portion. The fin is molded in a normal radially outwardly extending position and is rotatable about its fixed end into an adjacent recess in the skirt portion for permitting straight line axial removal of the top end closure from its mold. When the top end closure is assembled on the fiber tube, the fin is rotatable about its fixed end in the other direction from its normal position and is wedged between the skirt portion and the fiber tube to hold the top end closure on the fiber tube. A mold for making the top end closure is also disclosed which permits removal of the top end closure from the mold by straight line axial movement without requiring relative radial movement of portions of the mold.
